It would be B. 120 you would usually round up but the closest one to 129.02083 is 130 and since there is no 130 it would be 120
        
                    
             
        
        
        
Answer:
First Option 
Step-by-step explanation:
To graphically add two vectors a and b using the -tail and tip-method, you must draw the tail of b at the tip of the vector a. Then you must draw a line that goes from the tail of a to the tip of b. This line represents the sum of  .
.
In this problem, notice that the tail of the vector w is on the tip of the vector v. The line that joins the tail of v with the tip of w is u.
Therefore we can say that  .
.
The answer is the first option
